Re: find if eth0 up

[Jean-Francois Gobin <gobin@gobinjf.be>]

Here is the script ... Enjoy

#!/bin/bash

IFCONFIG="/sbin/ifconfig $1"

ISIT=`$IFCONFIG | grep "UP" | wc -l`;

if test $ISIT -gt 0;
 then
  echo "Yup ... $1 is up!";
else
  echo "Nope ... No $1 or it'sn't up!";
fi


TODO : 

Add a checker. You need one argument which is the device you're looking
for.
Suppress the error message if no device is present in the system.
